Cui Lizhe · Chuangan jishu xuebao · 2014
The energy consumption problem that exists in traditional time synchronization algorithm because of exchanging more packets to obtain synchronization accuracy. According to the special network structure in underground coal mine,on the basis of the analysis of bidirectional pair and one-way broadcast synchronization mechanism,combine both synchronization mechanisms with the transmission characteristics of radio effectively,and a twoway synchronization algorithm based on clusters structure which at the characteristics of the passive and low power is proposed. Experiments show that,synchronization algorithm which been proposed can solve the problems of exchanging packets frequently effectively,in the range of allowable error can reduce message consumption and balance the network energy.
